Legacy comparison operators. Note that these also test whether the set's elements were added in the same order!
template<typename ElementType, typename KeyFuncs, typename Allocator> static bool LegacyCompareEqual ( const [TSet](API\Runtime\Core\Containers\TSet)< ElementType, KeyFuncs, Allocator > & A, const [TSet](API\Runtime\Core\Containers\TSet)< ElementType, KeyFuncs, Allocator > & B )
